Abstract: 11,282. Tannett - Walker, F. W. June 21. Fluid - pressure hammers.-The head of a power hammer is raised by hydraulic pressure, compressing air during the upstroke, the compressed air, supplemented if desired by an additional supply, assisting in the delivery of the blow. The head c, Fig. 1, may be formed as a cylinder e, sliding in a fixed cylinder b and having a fixed piston i and rod h through which fluid is admitted to or exhausted from the upper side of the piston. Fluid is admitted, to raise the head, by operating a valve j by a handle k, the air in the cylinder b being then compressed and aiding in the delivery of the blow when the fluid is exhausted. The cylinder b may have a pipe containing a non- return valve communicating with the atmosphere, the pipe communicating with an air vessel and air compressor. Additional air pressure is thus available during the down-stroke, or if the compressor is not working, pressure may be raised in the air vessel by giving a few strokes to the piston, a stop-cock in the pipe being closed during the down-strokes. Other hydraulic means for raising the head may be employed. The head may move in guides and have two parallel cylindrical chambers for the hydraulic and air pressures respectively.
